The secondary air intake favours the carbon that was not burnt during the first combustion can suffer a post-combustion. This increases the
efficiency and assures that the glass keeps clean.
• In models of the Paris series (except for the model with lifting door: Paris 90V-G), Rioja and Coliseo, the secondary air intake control is
placed on the top of the door and its movement is from the left to the right. The higher entry air is corresponded with the higher side of
the triangle (see drawing D2.5).
• In Cairo series models, this regulation is located under the door. It is the regulation located on the right of the ash pan (see drawing
D2.6). The largest amount of air inlet coincides with the largest side.
• In the Londres and Londres-T models, this regulation is located under the door. It corresponds to the regulation located on the right.
The entry of a larger amount of air coincides with the regulation shifted towards the greater side of the triangle (See drawing D2.7).
• In all the others models this entry of air exists but it is not adjustable. It is usually placed on the top of the inside of the door, between
the door and the glass (see drawings D2.8, D2.9 and D2.10).
D2.5
Double combustion
Some models of inserts include a double combustion.
With this system we get a second preheated air input
inside the combustion chamber. This allows a second
combustion of the gases not burnt in the first combustion
that achieves a high performance efficiency, a great fuel
saving and reductions in pollutant emissions.
• In Cairo series models, this regulation is located
under the door. It is the regulation located on
the left of the ash pan (see drawing D2.11). The
largest amount of air inlet coincides with the largest side.
• In all the other models such as Mérida, Everest Visión, Everest and the
Paris, Madrid, Florida and Londres series, this entry of preheated air exists
but it is not adjustable. The air supply is usually made by little drillings on
the back wall of the combustion chamber (see drawing D2.12).
The combustion is not always stable. In fact, it can be affected by the weather
conditions or the outside temperature. This modifies the draught of the insert. For
this reason, our inserts have a baffle plate (or double baffle plate) and a draft-
diverter valve that controls and improves the draught.
Draught-diverter valve
The inserts of the Madrid and Cairo series (except Cairo-70 model) are provided with an adjustable draft-diverter
valve, with automatic opening that allows the control of the draught.
It is possible to place properly the draught-diverter valve when we open the door thanks to the screw on the
central higher of the frontal zone (turn right = open valve / turn left = close valve). The draught-diverter valve will
be opened automatically at the open of the door regardless of its position in order to avoid the exit of smoke to
the room (see drawing D2.13).
